Synthesis, structure and reactivity of oxovanadium(IV) schiff base complexes

چکیده
Oxovanadium(IY) complexes with schiff bases, viz., N,N'-bis(2-hydroxy benzylidene)benzidine (HBB), N,N'-bis(2hydroxy benzylidine)-p-phenylenediamine (HBP) and cinnamylidene-2-aminophenol (CAPh) have been synthesized and characterized by elemental analysis, molar conductance, electronic spectra, Fr-IR, IH-NMR, ESR, FAB mass, thermal and magnetic susceptibility measurements. FAB mass and thermal data show degradation pattern of the complexes. Square pyramidal geometry has been proposed for the complexes. The reactivity and substitution behaviour of the synthesized complexes have also been studied. Solid-state A.C. electrical conductivity studies reflect semiconducting nature of the complexes. The crystal system, lattice parameters, unit cell volume and number of molecules in unit cell of [YO(HBB)(H20hl complex have been determined by XRD, suggesting that the [YO(HBB)(H20hl complex crystallizes as tetragonal crystal system.

Bidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes
The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
